It is one of hundreds of icy TNOs (Trans-Neptunian Objects) that normally populate the Kuiper Belt girdling the solar system just beyond the orbit of Neptune. The problem is that 2000 CR105 is not normal. Its orbit is highly eccentric, with an aphelion 13 times farther out than Neptune's . This massive object (probably mostly ice) takes 3175 years to circle the sun. 2000 CR105 is real; it has been photographed; it is not Mirror Matter; no one blames any terrestrial extinctions on it. Nevertheless, we can and must wonder how its orbit became so badly distorted. Often in past years, whenever astronomers detected cometary orbits gone awry, they invoked Planet X; that is, some undiscovered massive body plying the outer reaches of the solar system. Indeed, there have been several intense and unsuccessful searches for Planet X over the years. (See Chapter AX in The Sun and Solar System Debris.) History seems to be repeating itself with 2000 CR105. Astronomer B. Gladman proposes that 2000 CR105 was forced into its present eccentric orbit by an encounter with a Mars-size Planet X that now orbits the sun at a distance about 15 times that of Neptune. From the standpoint of celestial mechanics, this perturbation of 2000 CR105's orbit is certainly within the realm of possibility. But two associated ...

Evolution Been Directed by Bacteria?With considerable fanfare, a multinational team of scientists has announced that the mtDNA (mitochondrial DNA) "squeezed" from a 29,000-year-old Neanderthal skeleton found in the northern Caucasus differs by 3.48% from the mtDNA of a 40,000-year-old Neanderthal skeleton from (fittingly) Germany's Neander Valley. Furthermore, both mtDNA samples differ from that of modern humans by a substantial 7%. These two innocent-appearing, widely publicized numbers have far-reaching implications: Modern humans and Neanderthals are only very distantly related, and they certainly never interbred, as suggested in many recent, popular articles; and Since neither Neanderthal mtDNA sample is closer to that of modern Europeans than it is any other modern human population, the so-called "multiregional" theory of human evolution and dispersion is unlikely to be correct. Thus, the out-of-Africa theory is favored;. These data and their implications stimulate several observations and comments; only one of which is mentioned in the references given below. F.H . Smith, an anthropologist from Northern Illinois University and a supporter of the multiregional theory, opines that 30,000-40,000 years ago the mtDNA of the early humans, who were mixing it up with the Neanderthals, was certainly very different from what it is today. Since mtDNA mutates rapidly, way back then human mtDNA might have been much more like that of the Neanderthals. (Ovchinnikov, Igor V., et al; "Molecular Analysis of Neanderthal ...

Ten million years after the dinosaurs may have roasted in a global firestorm, another methane burp may have erupted from the oceans. This burp was slower and did not ignite but was just as lethal. It filled with atmosphere with a highly effective green-house: methane. The result was a pulse of global warming; as seen in a 5-7 -deg C increase in the temperature of ocean-bottom water during that period. Biological evidence for the event occurs in the skeletons of marine animals that litter the ocean sediments laid down in that lethal period. On the land, prior to the methane release, North America was'populated by an odd assortment of unfamiliar mammals; "unfamiliar" to ustoday because they left no descendents. These archaic mammals succumbed to the effects of the sudden global warming and were ultimately replaced by the ancestors of our familiar deer, horses, and canines that streamed across the now-open Bering Land Bridge. Geology, too, provides evidence of this traumatic event. Ocean-bottom cores reveal landslide debris that was probably triggered by the sudden decomposition of great masses of methane hydrate. Seismic probes of the ocean sediments reveal chaotic zones suggesting a violent event. (Kerr, Richard A.; "A Smoking Gun for an Ancient Methane Discharge," Science, 286:1465, 1999.

It is not one gene coding for one protein, which then has a singular role in creating an operational human being. For example, some 5,692 genes are active in breast-cancer cells. Genes may also have multiple roles. Our present blueprint of the human genome does not display all the mobility and complex interrelationships of the genes. We do know that genes are the blue-prints for the manufacture of proteins. Of these, there may be over 1,000,000 different -- more than ten times the number of genes! These multitudinous proteins are continually being created and transported to where they perform their assigned tasks and are eventually deconstructed. It is this population of proteins (collectively the "proteome") that develops organisms and gives them life. We do not begin to have a blue-print for the proteome, which really tells us how life works. Then, there are epigenetic influences. "Epigenetic?" Yes, the manufacture of proteins according to genome blueprints is altered by chemical groups that attach themselves to strands of DNA. Methyl groups, for example, can completely silence genes. Scientists are strugglingto understand just how epigenetic factors affect inheritance and the creation of new species. There is much more to biology than DNA and genes.

Possible cultural and language links of Zuni to California, the social disruption at the end of the Heian period of the 12th century in Japan, the size of Japanese ships at the time of proposed migration, the cluster of significant changes in the late 13th century in Zuni, all lend further credibility to a relatively late prehistoric contact."

Were they the bones of pygmies or children of normal-sized tribes? The latter choice was made, and we hear no more on the subject -- at least on the standard academic circuits. But a few reverberations are still detectable elsewhere. V.R . Pilapil, for example, asserts that the disputed Tennessee graves really did contain pygmy remains. Not only that, but he hypothesizes that the pygmies arrived in ancient times from southeast Asia, probably the Philippines, where today's diminutive Aetas live. To support his case, Pilapil recalls B. Fell's examination of the Tennessee skeletal material. Fell noted that: (1 ) The skull brain capacity was equivalent to only about 950 cubic centimeters, about the volume of a non-pygmy 7-yearold; (2 ) The teeth were completely developed and showed severe wear characteristic of mature individuals; and (3 ) The skulls were brachycephalic with projecting jaws. Fell had, in fact, described skulls very much like those of today's adult Philippine Aetas. Another line of evidence adduced by Pilapil involved the traditions of British Columbia tribes, which recognized a tribe of very small people called the Et-nane.

Smolin in the journal Classical and Quantum Gravity (9 :173). At stake here is the very nature of Nature herself. We begin with the notion of anthropic cosmology, in which the physical constants of the universe are identified as having just the "right" values to allow the existence of stars, planets, carbon compounds, and the other ingredients of human life. (Just why this state of affairs prevails is a question rarely addressed!) Adherents of anthropic cosmology hold that our "human-friendly" universe is just one of many universes populating a larger metauniverse. These "other" universes are thought to have different values of the fundamental physical constants (viz., the mass of the proton) and, in consequence, wildly different forms of life. In nonhuman universes, there could even be entities for which our word "life" is inadequate. The second idea is that of an oscillating universe. In this concept, universes expand just so far and then collapse back into the "singularities" (i .e ., black holes) from which they arose. Then, Phoenix-like, they bounce back and reexpand into new universes -- ones with slightly different physical constants. These rebounding universes are in a sense mutated universes, which have been slightly modified during the physical trauma of collapsing into singularities. ...

Normally, they are radically different in design and frequency of operation. Crickets usually sing at frequencies above 3 kilohertz, and their ears are attuned to these high frequencies. The usual fly, on the other hand, hums and buzzes at only 100-500 hertz (cycles per second). Their ears are duly optimized at these frequencies. The cricket-hunting flies (genus Ormia ), however, would starve to death if they couldn't hear the highpitched cricket songs. Their response was to "evolve" a cricket-type ear so they could home in on their prey. This is a remarkable example of evolutionary convergence.

What follows is a long, highly technical computation of various probabilities, such as the evolution of intelligent life in the universe. All this (and there is a lot of it) leads to the following: "Making only the assumption that you are a random intelligent observer, limits for the total longevity of our species of 0.2 million to 8 million years can be derived at the 95% confidence level. Further consideration indicates that we are unlikely to colonize the Galaxy, and that we are likely to have a higher population than the median for intelligent species."

But do survey statistics prove that such paranormal phenomena are truly objective? The real nature of paranormal experiences, according to Ross and Joshi, lies in the close ties these paranormal phenomena have with dissociative phenomena (i .e ., automatic writing), hypnotic phenomena, and childhood traumas. They theorize: "A model is proposed in which paranormal experiences are conceptualized as an aspect of normal dissociation. Like dissociation in general, paranormal experiences can be triggered by trauma, especially childhood physical or sexual abuse. Such experiences discriminate individuals with childhood trauma histories from those without at high levels of significance."

On a different tack, one must ask why humans are subject to paranormal experiences at all, seeing as they seem to have no survival value and should have been weeded out by natural selection long ago!

Therefore, if solar radiation levels (proportional to sunspot numbers) are high near her time of birth, her entire inventory of eggs will be bombarded by high levels of solar radiation.

In retrospect, this is not surprising. By 1700, the cities of the 1540s had been swallowed up by the jungle. Besides, most thought, the conditions in the lowland tropics are too harsh to nourish advanced societies.

Well, the dozen or so other theories that have been advanced to account for whale strandings haven't been much better. M. Klinowska thinks that she has some clues indicating a better theory. First, all whale strandings (in Britain, at least) occur where magnetic field contours are perpendicular to the shoreline. Second, strandings are also correlated with irregular changes in the magnetic field. You will see the significance of these facts after you hear her theory.

Dennison et al point out that relative to non-Antarctic falls, the Antarctic population is underabundant in iron and stony iron meteorites, among others." Trace-element studies: ". .. demonstrate a statistical unlikelihood that both sample populations derive from the same parent population." One reason for the differences is that the Antarctic ice has been accumulating meteorites for many thousands of years longer than modern man has been picking up non-Antarctic meteorites. (Lipschutz, Michael E., and Cassidy, William A.; "Antarctic Meteorites: A Progress Report," Eos, 67:1339, 1986.) Comment. If Antarctic meteorites differ because they impacted the earth over a longer span of time, it must be that the meteor population in the vicinity of the earth has been changing. Why?

... the proponents of Darwinism were delighted when the geologists presented them with almost endless periods of time in which evolution could progress in small steps from species to species. Now, in a strange turn-about, a creationist writer is using evolutionary theory to infer a very short history for the formation where geologists want a good deal of time. We quote from the conclusion of J.R . Meyer: "If any group of animals were ever going to undergo significant degrees of evolution from parent stock and obtain resultant speciation, surely the Kaibab squirrel would be one of the more likely candidates. Supposedly isolated from their neighbors for hundreds of thousands of generations over a period of at least several million years, and significantly violating virtually every restriction of the Hardy-Weinberg equilibrium for the non-evolving population, these organisms, even by creationist standards, should have undergone significant and detectable changes. In reality all they show are moderate changes, primarily in two coat color characteristics for part of their population. To make things even worse, this species is known to have a highly variable coat-color polymorphism throughout its range. Thus, even the differences displayed appear to be easily accounted for by several mutations and a slight change in gene frequency for one or two loci, all occurring in a limited period of time. "If an organism such as the Kaibab squirrel is able to escape all but a few minor changes in coat color (and these of dubious survival value) given the supposed immense time of rather complete isolation and violation of the Hardy-Weinberg equilibrium, we must ask ...

Science Frontiers ONLINE No. 41: Sep-Oct 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Wimps in the sun?For over two decades now, physicists have been measuring the neutrino flux emitted by the sun -- and despite all attempts this flux is much too low. It just doesn't jibe with what theorists say should be happening in the thermonuclear powerhouse in the sun's interior. J. Faulkner and R. Gilliland have conceived a solution to this dilemma. They postulate a large population of WIMPS (Weakly Interactive Massive Particles) orbiting the sun's core, but still well beneath the sun's visible surface. The WIMPS help convey heat out of the core, thereby cooling it to temperatures significantly less than those predicted by the astrophysicists. A cooler core emits fewer neutrinos, bringing theory into line with reality. And just what are these WIMPS? One suggestion is that they are photinos, a particle suggested (but not proved) by recent experiments at CERN (SF#37) (Thomsen, D.E .; "Weak Sun Blamed on WIMPS," Science News, 128:23, 1985.) Comment. WIMPS represent just the kind of particle that Dewey Larson railed against in his book: The Universe of Motion. He maintains that astronomers have to engage in such ridiculous theoretical gymnastics and invention only because they have picked the wrong energy-generating mechanism for stars and refuse to give it up! Larson's theory, on the other hand, solves this ...

Science Frontiers ONLINE No. 50: Mar-Apr 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Too many short-period comets Some comets, such as Halley's , have periods of less than 200 years. Scientists have postulated that these comets, which orbit relatively close to the sun, originally came from the far-distant Oort Cloud on parabolic (non-returning) orbits around the sun. Perturbations by the planets, notably Jupiter, deflected them into the tighter orbits we see today. The problem is that the number of parabolic comets entering the inner solar system from the Oort Cloud of comets (located at the outermost fringes of the solar system) is 100 times too small to account for the existing population of short-period comets. M.E . Bailey believes this discrepancy can be removed if the Oort Cloud possesses a massive inner core of comets. (Bailey, M.E .; "The Near-Parabolic Flux and the Origin of Short-Period Comets," Nature, 324:350, 1986.) Reference. The Oort Cloud of comets is an entrenched part of astronomical dogma. For observations challenging its existence, see our catalog: The Sun and Solar System Debris. A description of this book may be found here .

... terrestrial life in a recent issue of BioScience. The earth, it appears, is a veritable Gene sis Machine; and it is only one planet among a possible infinitude. So many terrestrial species have already been described that one could easily believe that biological collectors roaming the planet's wild places have just about completed their task. Some recent totals: 47,000 species of vertebrates, 440,000 plants, and 751,000 insects. But we may not even be close to grasping life's diversity on earth! We do well in counting the large mammals and birds, but most insects and microscopic forms of life have escaped description. To illustrate, in 1964, the British ecologist C.B . Williams, combining intensive local sampling and mathematical extrapolation, extimated the insect population as 3 million species. However, by 1985, this figure has been raised ten-fold to 30 million species. Why the huge jump? For the first time, entomologists had found a way to efficiently sample the canopies of tropical forests. This rich stratum between the sunlight and gloomy forest floor 100+ feet below had been largely neglected before. The slick tree trunks and the attacking swarms of wasps and stinging ants deterred the insect counters. What the collectors did was to fire projectiles with ropes over the high branches and then haul up canisters of a knockdown gas. Insects rained down -- a cloudburst of new species -- neatly collected on sheets spread out below. Such techniques led to the 30-million figure. As Wilson put it, "The pool of diversity ...

Science Frontiers ONLINE No. 42: Nov-Dec 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A Large Quasar Inhomogeneity In The Sky "In an area roughly 20 x 70 on the sky, there exists an excess of bright, high-redshift quasars. Quasars with this distribution of apparent magnitude and redshift have a negligible chance of being drawn from the population of quasars present in other areas of the sky. At a mean redshift distance corresponding to their average z = 2, these quasars would represent an unprecedented inhomogeneity over enormous volumes of space in the universe." It is difficult for astronomers to accept such a large "bubble" in the cosmos, because the Big Bang Theory basically produces a "smooth" universe. The author of this paper, H. Arp, comments that the size of the inhomogeneity could be shrunk considerably if redshifts were not taken as measures of distance.

... the Galapagos. These islands are no older than 3-4 million years. The unique terrestrial life forms had to develop in less time than this. (Hickman, Carole S., and Lipps, Jere H.; "Geologic Youth of Galapagos Confirmed by Marine Stratigraphy and Paleontology," Science, 227:1578, 1985.) Comments. Several remarks seem appropriate here: (1 ) The varied fauna and flora of the Galapagos did not evolve independently; viz., the bills of the Darwin finches are tailored to specific food sources (plants). Many species changed rapidly and in concert. (2 ) A recent Science article (228: 1187, 1985) notes that inbred mice often evolve different morphological characteristics very quickly. This observation probably applies to the initial Galapagos populations, which must have been small and inbred. (3 ) Harking back to the item on the Guadeloupe skeleton, the Galapagos display similar strata of limestone, beach rock, etc. Until now, the limestones had been dated from the Miocene to the Pleistocene, but according to Hickman and Lipps they must be much younger than Miocene. The Guadeloupe dates may also be in error. Caveat emptor. From Science Frontiers #40, JUL-AUG 1985 . 1985-2000 William R. Corliss ...

But as in so many other cases, the real story is turning out to be more complicated than the biologists first thought." Several details don't match the moth propaganda. For example, all the photos show the moths resting out in the open on tree trunks, whereas they actually rest inconspicuously under branches and where branches join the tree trunk. (Cherfas, Jeremy; "Exploding the Myth of the Melanic Moth," New Scientist, p. 25, December 25, 1986.) Comment. Since no new species of moth have arisen (merely population shifts between dark and light phases), why do evolutionists make so much out of this?
